Benefits

DSU™ has many advantages when compared to conventional upgrading including:

Simplification of the upgrading process and reduction of downstream upgrading/processing requirements:

The reactivity of sodium allows for the removal of many conventional process units such as Claus Plants, cokers and hydrocrackers by combining sulphur removal, metals precipitation and upgrading in one simple step. When additional downstream processing is required, The DSU™ process removes many of the contaminants that impact optimal performance of downstream processing units and catalysts. DSU™ produces a sweet, upgraded heavy oil equivalent that requires minimal downstream processing prior to refining or for use as a low sulphur fuel oil.

Reduction of diluent:

The near pipeline ready DSU™ product can be put into the pipeline and shipped to market, significantly reducing the diluent needed for transportation and therefore greatly increasing the capacity of existing pipelines.

Scalability and modularity to upgrading:

The process equipment in DSU™ is fully scalable, allowing for a modular or permanent process configuration with many potential applications including:

          ... field upgrading of bitumen from SAGD production

          ... on site production of low sulphur fuel oils

          ... "straddle" conversion of diluted bitumen from export pipelines

          ... integration with other upgrading or refining complexes or

          ... large scale upgrading


The bottom line... DSU™:

          ... converts heavy sour feeds such as oil sands bitumen into a sweet heavy oil equivalent with no metals or acid content (TAN);

          ... converts vacuum residual and low value feedstocks into a low sulphur fuel oil equivalent;

          ... minimizes the diluent required for pipeline transportation;

          ... has the potential for greatly improved economics and

          ... greatly reduced carbon emissions when compared to conventional desulfurization and upgrading technologies.
